Ukusetshenziswa okuyinhloko kwe-latex powder ephindwe kabusha
Impushana efakwa odongeni yangaphakathi nangaphandle, okokunamathisela okunamathayili, i-ejenti yokukhomba, i-ejenti yokusebenzelana kwempushana eyomile, udaka lwangaphandle olushisayo olufakwa ezindongeni, udaka oluzilinganisa, udaka lokulungisa, udaka lokuhlobisa, udaka olungangeni manzi lwangaphandle olushisayo oluxutshwe nodaka. Odakeni, okokuthuthukisa ukuqina, imodulus enwebekayo ephezulu kanye nobunye ubuthakathaka bodaka lukasimende lwendabuko, kanye nokunikeza udaka lukasimende ukuguquguquka okungcono namandla ebhondi eqinile, ukuze limelane futhi libambezele ukukhiqizwa kokuqhekeka kodaka lukasimende. Njengoba i-polymer kanye nodaka lwakha isakhiwo senethiwekhi esingena ngaphakathi, ifilimu ye-polymer eqhubekayo yenziwa ezimbotsheni, eqinisa ukubopha phakathi kwama-aggregates futhi ivimbele ezinye izimbotshana odakeni, ngakho udaka oluguquliwe ngemuva kokuqina lungcono kunodaka lukasimende. Kukhona ukuthuthuka okukhulu.
Izakhiwo zomkhiqizo ze-latex powder ehlakazeka kabusha
1. Thuthukisa amandla okugoba namandla okugoba odaka
Ifilimu ye-polymer eyakhiwe i-polymer powder ephinda ihlakazeka inokuguquguquka okuhle. Amafilimu akhiwa ezikhaleni nasezindaweni ezingaphezulu zezinhlayiya zodaka lukasimende ukuze akhe ukuxhumana okuvumelana nezimo. Udaka lukasimende olusindayo noluphukayo luba nokunwebeka. Udaka olungezwe ngempushana ye-latex ehlakazeka kabusha luphakeme ngokuphindwe kaningana ekuqiniseni ukumelana nokuguquguquka kunodaka olujwayelekile.
2. Thuthukisa amandla okubopha nokuhlangana kodaka
Ngemuva kokuthi impushana ye-latex ehlakazeka kabusha njengesibophezelo sezinto eziphilayo kwakhiwa ibe ifilimu, ingakha amandla aphezulu okuqina kanye namandla okubopha kuma-substrates ahlukene. Idlala indima ebalulekile ekunamatheleni kodaka ezintweni eziphilayo (EPS, ibhodi legwebu elikhishwe) kanye nama-substrates angaphezulu abushelelezi. Ifilimu ye-polymer rubber powder isatshalaliswa kulo lonke uhlelo lodaka njengento yokuqinisa ukukhulisa ukuhlangana kodaka.
3. Thuthukisa ukumelana komthelela, ukuqina nokumelana nokugqoka kodaka
Izinhlayiya ze-raber ze-powder zigcwalisa umgodi wodaka, ukuminyana kodaka kuyanda, futhi ukumelana nokugqoka kuyathuthukiswa. Ngaphansi kwesenzo samandla angaphandle, izokhiqiza ukuphumula ngaphandle kokubhujiswa. Ifilimu ye-polymer ingaba khona unomphela ohlelweni lodaka.
4. Thuthukisa ukumelana nesimo sezulu kanye nokumelana nokuncibilika kodaka, futhi uvimbele udaka ekuqhekekeni
I-redispersible latex powder iyi-resin ye-thermoplastic ene-flexible eguquguqukayo, engenza udaka lubhekane nokushintsha kwendawo ebandayo yangaphandle neyokushisa, futhi ivimbele ngokuphumelelayo udaka ekuqhekekeni ngenxa yokushintsha umehluko wokushisa.
5. Thuthukisa i-hydrophobicity yodaka futhi unciphise ukumuncwa kwamanzi
I-latex powder ehlakazeka kabusha yenza ifilimu emgodini nangaphezulu kodaka, futhi ifilimu ye-polymer ngeke iphinde ihlakazeke ngemva kokuvezwa emanzini, okuvimbela ukungena kwamanzi futhi kuthuthukise ukungakwazi ukungena. I-latex powder ekhethekile ephindwe kabusha enomphumela we-hydrophobic, umphumela ongcono we-hydrophobic.
6. Ukwenza ngcono ukusebenza kokwakhiwa ngodaka
Kunomphumela wokugcoba phakathi kwezinhlayiya ze-polymer rubber powder, ukuze izingxenye zodaka zikwazi ukugeleza ngokuzimela. Ngesikhathi esifanayo, i-powder yenjoloba inomphumela we-inductive emoyeni, inikeze ukucindezelwa kodaka futhi ithuthukise ukusebenza kokwakhiwa kodaka.
